Title: Catch invalid launch direction and log

Matching CompassDirection.Enum with a user generated content string is prune to cast an IllegalArgumentException and drive the plugin event control to hell.
So catch the exception and log the unknown direction string with world name and coordinates of the sign block for review by an admin.
